Rather than focus on the model, I think I would focus on the words. For me, and in my interpretation, the issue is around good faith. Physicians who act in good faith under the law should be immune from prosecution. Whether it's bad faith, indifference, or a casual approach, that would exclude them from this protection, but I believe the vast majority of physicians will participate in good faith. They should be protected under the law under that specific wording.
